These two statements appear in the explanation for pruning weigelas:
“Trimming weigela bushes right after they bloom will keep you from inadvertently pruning off next year’s flowers.”
“Pruning weigelas after blooming means that you will be pruning before the blooming wood has a chance to grow.”
Are these contradictory, or am I misunderstanding?
These two statements compliment each other. The first statement, in broad terms, states that pruning after the blooms fall off will keep you from cutting new blooming shoots off, because the next blooming shoots will not have formed yet, and the second statement reiterates that.
